How to join the new Disc to Digital program?

Game disc replacement program is to replace discs with a new discs it would be thru the publisher EA in this case not for digital codes

There are somethings digital exhange offers but those are rare and only ms did it for the halo 4 legendary editions

I usually get only digital to avoid disc issues, if the disc is new, you could try contacting the developers, some have a replacement disc program

You could check with Rockstar to see if they have a disc replacement program, buy a new one, or buy it digitally. Copying the disc would both be illegal and would not work.

You could try contacting Ubisoft to see if they have a disc replacement program, otherwise you would either have to purchase a new disc or purchase the game digitally.

There is no program to transfer a physical copy of the game to a digital copy. When you put the disc in it installs the game to the hard drive, as is necessary, but does not make that a digital copy. It still requires the disc and verification to play.
So if you have a new console, then you will need to use the disc to install the games on the new console, and continue to use that disc to play. If you have an all digital and there is no disc, then I would see if you could still return the console to get
one that has a disc drive, or look at purchasing digital titles or downloading free titles such as Fortnite on the Xbox One S All Digital edition.
